Abstract

En vue d'empêcher la détérioration de l'adhérence secondaire résistante à l'eau qui survient en cas d'utilisation prolongée d'une composition liquide de phosphatation par conversion, contenant des fluorures, servant à phosphater par conversion des surfaces métalliques au moins partiellement aluminifères, la boue contenant le composé d'aluminium qui se forme dans ladite composition pendant son utilisation est coagulée et sédimentée du fait de l'adjonction à cette même composition d'au moins un coagulant cationique polymère.
